Force System with Vertical V-Bends: A 3D In Vitro Assessment of Elastic and Rigid Rectangular Archwires Madhur Upadhyay1, Raja Shah2, Sachin Agarwal3, Meenakshi Vishwanath4, Po-Jung Chen5, Takafumi Asaki6, Donald Peterson7 1Division of Orthodontics, University of Connecticut Health, 2Private Practice, 3Department of Orthodontics, University of Melbourne, 4Department of Orthodontics, University of Nebraska Medical Center, 5Department of Craniofacial Sciences, University of Connecticut Health, 6Biomedical Engineering, University of Hartford, 7Department of Mechanical Engineering, College of Engineering and Engineering Technology, Northern Illinois University The method presented here is designed to construct and validate an in vitro 3D model capable of measuring the force system generated by different archwires with V-bends placed between two brackets. Additional objectives are to compare this force system with different types of archwires and to previous models.

An Efficient Biomechanical Approach for the Management of an Impacted Maxillary Central Incisor American Journal of Orthodontics and Dentofacial Orthopedics : Official Publication of the American Association of Orthodontists, Its Constituent Societies, and the American Board of Orthodontics. Aug, 2014 | Pubmed ID: 25085308 Treatment of an impacted maxillary central incisor poses a unique challenge to the orthodontist because of its position within the esthetic zone, requiring careful management of the soft tissues and an effective biomechanical setup for alignment. This article describes a novel method of extending an extrusion wire from cross tubes attached on the base archwire for forced eruption of impacted central incisors. The effectiveness and versatility of this method are demonstrated with 2 patients.
Force System Generated by Elastic Archwires with Vertical V Bends: a Three-dimensional Analysis European Journal of Orthodontics. Apr, 2017 | Pubmed ID: 27287313 Our previous understanding of V-bend mechanics is primarily from two-dimensional (2D) analysis of archwire bracket interactions in the second order. These analyses do not take into consideration the three-dimensional (3D) nature of orthodontic appliances involving the third order.
